Hi,
Hardware: HPE J9780A Switch 2530-8-PoEP
Did some digging, thanks to the very helpful new? tool https://mibs.observium.org/mib/HP-ICF-POE-MIB/#hpicfPoePethPsePortPower
It appears the PoE Power warning is based on being over poe (not poe+) limits, not sure how it determines what the maximum allowed should be. For PoE+ Switches it is 30W
The seemingly undocumented OID .1.3.6.1.4.1.11.2.14.11.1.9.1.1.1.16 gives the following output:
.1.3.6.1.4.1.11.2.14.11.1.9.1.1.1.16.1.1 = 1 .1.3.6.1.4.1.11.2.14.11.1.9.1.1.1.16.1.2 = 1 .1.3.6.1.4.1.11.2.14.11.1.9.1.1.1.16.1.3 = 2 .1.3.6.1.4.1.11.2.14.11.1.9.1.1.1.16.1.4 = 1 .1.3.6.1.4.1.11.2.14.11.1.9.1.1.1.16.1.5 = -1 .1.3.6.1.4.1.11.2.14.11.1.9.1.1.1.16.1.6 = 2 .1.3.6.1.4.1.11.2.14.11.1.9.1.1.1.16.1.7 = 1 .1.3.6.1.4.1.11.2.14.11.1.9.1.1.1.16.1.8 = -1
Ports 1,2,4 and 7 have PoE devices attached. Ports 3 and 6 have PoE+ devices and ports 4 and 8 are disconnected.
This table matches the 'PLC Type' column in the switch GUI.
Hopefully this could be useful in making more meaningful PoE Power status warnings/alerts.
Also not sure why Current causes an alert.. We have 3 of these switches, some of which show 0.22A as ok, while other ports alert as low as 94mA
These will just be getting the "default" sensor limits, which is measured +/- some amount. Probably not too useful for PoE.
Since these sensors are from a POE-specic OID, we can hardcode the limits to anything we like, or disable them. Is there some standards-based limit, or should they not alert at all?
I'm not overly familiar with the requirements here.

HI all,
in the past months I did some projects with PoE (PoE Splitter for powering Bosch Smart Home Controller, Philips Hue, Cromecast etc pp. If classic PoE is activated it can be up to 12.95W/15.40W, PoE+ means 25.50W/30W.
